Development of flowable ultra-lightweight concrete using expanded glass aggregate, silica aerogel, and prefabricated plastic bubbles

Low energy consumption buildings is one of effective responses to the challenge of climate change. Lightweight cement-based composites with excellent thermal insulation and mechanical properties are sustainable building materials for energy-efficient buildings. In this study three different types of lightweight thermal insulating materials, namely expanded glass aggregates, silica-aerogel, and prefabricated plastic bubbles, were tested as...
